Firefox 社群討論區

Several weeks ago, I was attempting to upgrade from Windows 10 to Windows 11. In the process, I deleted Firefox (using Revo Uninstaller) and then reinstalled it, downloading it from the Mozilla website. Unfortunately, it didn’t run, giving me, at different attempts, different error messages. In the time since then, I have read many suggestions from many different websites and I have tried some of these suggestions, all with no success – until today. I have just completed the suggestions made on https://support.mozilla.org/en-US/questions/1327628 and Firefox is now back, working. I am happy and grateful, but not finished. None of my personal data came with the currently functioning version of Firefox. Since the re-emergence of Firefox, I have been reading several websites dealing with copy, backup and restore of my Firefox profile. Right now, the path C:\Users\rsuth\AppData\Roaming\Mozilla\Firefox\Profiles\ shows 5 folders: Two of the folders show 11/11/24 as the date modified (probably the date of the download from Mozilla). The folder 0dppjrfa.default contains one file, times.json, dated 8/11/2020. The other folder, ru82tlj5.default-release, has 97 items, most dated 11/11/2024. The remaining three folders are all dated 12/2/24 (today, as I write this). One folder’s name ends .default, the second name ends .default-release, and the third name ends .default-release-thirteen digits. The question that I am asking here is what do I do next to, hopefully, bring back the personal date I had with Firefox before my updating to Windows 11. Should I delete the folders dated 12/2/24? What, if anything, is the significance of the folder whose name ends in 13 digits? I’m hoping someone will be able to tell me how to fix these Firefox problems. And if I can, then I hope to be able to do something similar to help me bring back Thunderbird as well. Thunderbird became unfunctioning at the same time as Firefox. Thank you.

Hello, I've got a bit of an issue with Sync. So, my current sync profile is outdated by ages, and I'd like to delete it completely and update it with all of the information on my desktop browser. But, when I try to enable sync on my desktop it overwrites my desktop profile with all of the outdated information saved on Sync. I can't seem to find anywhere to delete the saved Sync data so that I can upload a new copy.

I hope someone can help, thank you!

When I sync my Firefox account, my old data, themes, and add-ons come back. There are add-ons, themes, passwords, and usernames from 3-4 years ago that I no longer use. How can I reset my sync data and sync again? In short, there is an 'overwrite' situation; the old data remains while the new data is synced over it.

Hi, I hope someone can help me. Please note I live in UK and I have a Desktop Computer but do not have a mobile phone. I use Firefox browser. This is what happened over 2 days Thurs and Friday. 28-11-24 THURSDAY @1.38pm On Thursday morning I used my computer with Firefox browser, and it worked perfectly OK. Then I had to go out shopping @11-15am. When I came back in doors @1.38PM I turned on my computer, it booted up as normal, then a Blue Screen appeared, with a message from Microsoft re back up in Cloud. I have not actually used Cloud before, although I did try to set it up earlier this year but not completed. So, I thought I would try again. This time I tried to register for the first time on cloud, I entered my email address and country, date of birth and then a password. Maybe something else, can't remember.

Then it asked for a code number that it said it had sent to my email, but I could not get that email then as I was stuck in between booting up and the Desktop screen. ( I DO NOT HAVE A MOBILE PHONE) As I did not have the code number, I clicked on, what may have said “not now” or similar message. Anyway, it would not continue so I had no option than to press the back button arrow, top left corner, several times. I think it took me back to the page with choices. I think I clicked remind me in a few days, which took me to the Desktop.

Normally my computer automatically opens Firefox Browser, but this time, I had to open Firefox, still no problem so far and the rest of Thursday OK. I did not try Microsoft Cloud again on Thursday.

29-11-24 Friday @ about 10.15am I thought that when I booted up, it may go back to where I left it Thursday, but no. When I turned on, there was no sign of the Blue Screen or Microsoft Cloud message re Back Up. When computer reached the Desktop, it did not load Firefox but an ERROR MESSAGE. It said. ERROR: PLATFORM VERSION "133.0" IS NOT COMPATABLE WITH MINVERSION >= 132.0.2 MAXVERSION <= 132.0.2 MAYBE TRY TO REINSTALL FIREFOX

It worked perfectly well before I tried to set up Microsoft Cloud yesterday (Thurs 28-11-24) now I cannot load or use Firefox at all, because it comes up with the same message every time. I have tried turning the computer off and back on, no luck.

My worry about Reinstalling Firefox is that I have hundreds of websites saved in bookmarks folders and I am not sure if I would lose them.

At this moment I have had to endure Microsoft Edge which I don't like. Don't put me through any more pain. Can you please help out a pensioner lost in the modern technological world. Thank you David

After a routine system restart due to display driver crash my Mozilla Firefox ceased to work, displaying a broken link. After some messing around I decided to reinstall the application, but when I did it was an entirely new instance with none of my local saved data (bookmarks, passwords, history etc). I've been able to restore my bookmarks, but not my passwords. I've found the relevant key4.db and logins.json files pertaining to the older intall, but I have no idea how (if possible) to install them, and I assume there would only be a compiled csv if I created it.

Help!

I've never had this problem before, even though I've been using Firefox for 4 years. As soon as I try to connect to an account via Google, or go to Docs/Drive/Classroom, I'm always taken to a “Clear cache and delete cookies” page. So I followed the instructions on the page, deleted all my data and saved cookies from Firefox and even tried to reinstall Firefox completely, but nothing changed, I'm always redirected to this page.

Someone can help me please? I can provide more informations if needed.

Hi, A few weeks ago, I wanted to sync my open Firefox tabs between my old laptop and my new one. I signed in to my Mozilla account on both computers, and the sync process worked just fine. For weeks, my synced tabs appeared in my Firefox sidebar on my new laptop, and all was good. However, the other day, I had to restart my computer a few times, and when I open Firefox again, my synced tabs were gone. On my Mozilla account page, it still says that I am signed in to my old laptop. How can I see my synced tabs again? Thank you very much for your help!

For example, say, you have 3 opened tabs in a Firefox (FF) windows. Normally, when you close FF and then re-open FF, it restores 3 previous opened tabs.

But, if you have another FF windows opened at the same time, when you close the FF windows with the 3 opened tabs and re-open back a new FF windows, FF won't restore the 3 opened tabs.

Same thing happens when you have another Private FF windows at the same time, when you close the non-Private FF with the 3 opened tabs, and then you re-open FF, it loses the 3 opened tabs.

That's why you can see 'countless' question about lost opened session, because of the issue above along with crash etc.

Is this a bug or a known feature?

Hello,

Referring to your article [https://mzl.la/3TS8WcA] (Import settings and data into Thunderbird for Android) . The first step is : Export Thunderbird Desktop settings

   Click ≡ > Tools > Export for Mobile. 

However, I am running version 128.3.3esr (64 bits) "Nebula" and the menu "Export for Mobile" isn't available under "Tools" as mentioned in the article.

Please advise

Regards

The Firefox Sync system is really neat for keeping our booksmarks synced across devices, but what I would also love to see is the option to sync all settings as well, including the changes made in the "about:config" settings.

Across my years of browsing I changed quite a lot of small little things and having to track all of those down every time I set up a new device or reinstall windows can get a bit tedious, so I was wondering if those settings can also be included in the Sync settings somehow - or if such a feature might be planned for the future?

HI! I have my phone synced to my destop firefox, and just synced my laptop, microsoft windows 11.

everytime I want to access a synced page, like gmail, or my trading brokers page, it asks me to login again, so its synced, but have to relogin every time I open the firefox browser, or even when I simply close the tab. I never have to log in repeatedly on the desktop.

Also, my favourite extension Tab Stash, is missing features in this firefox browser. I have tested everything to get it to work, including clearing the cache, restarting. normally you can right click a firefox tab like the attached image, and choose "open Tab Stash in a Tab". and other options. but they dont show in this synced version of the browser. Very weird and frustrating. I must get this to work as I manage hundreds of saved tabs and folders through Tab Stash which is only available on Firefox.

I dont know how to contact the extension creator, I cant see any contact link on his gitHub.

I am currently running Firefox on Windows 11 (24 H2) and today, like I have usually done a lot over the past years I opened Firefox, did some browsing, then I quit the app. When I later opened Firefox (version 130.0.1 (64-bit)) no a single of my open windows got restored.

I have been relying on Previous session being restored. Today however, it did not work, and the option to use "hanburger menu" -> History -> Recently Closed Windows" do not show my windows I had open.

How can I find my old sessions? Can I restore them somehow from backed up data?

Dear sir

I use Firefox on Ubuntu Linux, and it works fine.

For unrelated reasons I have created a new Linux Mint 22 boot partition, and I would like to use the same Firefox profile on both Linux OS-s, without having to move or copy the existing profile I use on Ubuntu. (The profile is placed on a third independent data partition!) I cannot find any information on how to do it. All information I find involves moving the profile, but then Firefox on Ubuntu would not be able to continue to use it.

I look forward to hear from you. Thank you. :-)

"how to revive return all 124 tabs of prior sessions ? in Firefox...older version ? please help. & How to avoid if close by mistake 1 window with all ....vs 1-2 tabs only ? " HOW revive replace lost all tabs 4 days ago ? '

Dear Firefox,

I have just reinstalled my operating system after some issues. After reinstalling my browser, I logged into my browser after changing the password, but now no data is being synced. The open tabs, bookmarks and saved passwords were the most important, but none of that has synced back. After waiting for a little bit I decided to press the synchronize now button, but that also didn't do anything. Is there perhaps something wrong with the syncing right now? Or is there another way to get that data back? I didn't save it as I normally don't have to.

Thank you for your reply!

Kind regards, Lili

Hello, FireFox community!

I use FireFox on desktop at home, at work and on mobile.

Recently I made an account at home.

When I log in to my account at work and sync which bookmarks (and settings) will last?

Which is the primary device?

Will my work bookmarks be replaced by these from home PC or will be supplemented?

I will appreciate your help!

Best wishes!

I had a number of tabs open when my phone rang. After the call I checked the browser, and most of the tabs were gone. Usually there is an option to "restore previous session" in History, but it is not there now. I would like to go back to that previous session. Is there a way to do that?

We deploy Firefox via a software called Pulseway and last night it reinstalled Firefox over the current installation for one of our users. When he logged in this morning, all his data was missing from the browser as it appears to be a fresh installation. I'm unable to find his previous profile in the AppData folders (checked by going to about:profiles and opened each profile). There is no backup for this info, and he did not have a Sync account set up. Is there anywhere else I could possible recover this data for the user? Thanks in advance.
